I have a DeWalt miter saw. Have had it a couple of years. I noticed the other day that the blade wobbles. What happens is as it starts up to speed everything is OK, but after 10-15 seconds the blade wobbles. It appears to be secure to the motor arbor and the motor appears to be secure. Is my blade warped or what?

If the blade was warped it would be immediately apparent. You might have just the normal runout that shows up with wear. Mine is 10 y/o and has about 1/64" runout.
I had a DeWalt miter saw and it developed a wobble in it too. It made a ripple across the cuts, much more then a common kerf mark. I replaced the blade to no avail, then I replaced the saw with a new Makita LS1013 and ShaZam! The wobble disappeard along with the saw. I think the bearings had worn out as the saw did have a lot of heavy use on it.
The blade that came with my DeWalt DW706 is a thin kerf variety. It would create a skewed cut (very slight), especially when doing miters. I replaced it with a beefy crosscut blade and get perfect cuts now. Apparently, the thin kerf blade was twisting a tiny bit as it went through the wood.
